gianni,

the info is in the manual which if you don't have it... you could do a search for the pdf.

I forget the exact location... but if you browse through the camera's menu you'll find it under "flange back adjustment" or something like that.

LCD must be in the closed position
LCD B. Light switch (under top handle) must be in the OFF position
Gain must be set to H
I found that if you help...

Press and hold Cancel + Jog Wheel, then + Menu
Maintenance, RPN and Information Menu items will be added to bottom of Menu below Others
Flangeback auto adjustment (also called back focus) is under Maintenance, shown as Auto FB Adjust

Procedure is the same as the EX1-

An 8" or larger Seimens star chart is ideal. Siemens star - Wikipedia, the free encyclopedia
It should be mounted on a plain wall, wide enough to cover most of the frame at Z0, widest angle
Other high contrast objects within this field of view may effect the calibration
Mount the camera on a tripod, about 10' away from the high contrast back focus target
Zoom all the way in to the target and center it in the viewfinder
Set lens to Auto Focus, Focus Ring pushed forward, Auto Iris, Macro Off
Select Auto FB Adjust in the Maintenance menu
Select Execute
